The results of a study of the compound nucleus [sup 114]Cd by neutron time-of-flight spectroscopy methods are presented. Targets of both natural cadmium and cadmium enriched in the 113 isotope were used. The neutron total capture and neutron transmission were both measured. A total of 275 new resonances were located. In addition, 102 other resonances which were previously known but not assigned to a particular cadmium isotope were definitively assigned to [sup 113]Cd. Resonance parameters [ital E][sub 0] and [ital g][Gamma][sub [ital n]] were obtained for both newly identified and previously known resonances. Of the 437 resonances now known in [sup 113]Cd, we identify 104 of them as [ital l]=1 based on their small widths. Strength functions and level spacings are obtained for both [ital l]=0 and [ital l]=1 resonances. Comparisons of the data with Porter-Thomas reduced width distributions, Wigner nearest neighbor spacing distributions, and the Dyson-Metha [Delta][sub 3] statistic are given. The linear correlation coefficient between adjacent spacings is also discussed. The spectroscopic information obtained is of importance for planning and interpretation of parity violation measurements on the [ital p]-wave resonances of [sup 113]Cd.
